Multiple-input multiple-output (MIMO) antenna systems use multiple sets of antennas to increase the capacity of a radio link, or to send and receive multiple simultaneous data signals over the same radio channel. It’s become an increasingly integral part of wireless and mobile data networks, from the earliest generations of wireless internet to cutting-edge 5G systems. The coming 6G networks will also rely on 6G antenna systems, making it all the more critical for the next generation of engineers and antenna designers to have a firm grasp of this foundational technology.
MIMO Antenna Systems for 5G and Beyond offers a timely introduction to these systems and their design principles. Incorporating the latest designs and a comprehensive overview of current system configurations, it provides complete design procedures and performance metrics for MIMO systems. The result is a one-stop shop for all MIMO applications and wireless standards.
MIMO Antenna Systems for 5G and Beyond readers will also find: - The first book ever to cover MIMO design practices specific to 5G wireless communications - and beyond- Detailed discussion of MIMO configurations including passive, reconfigurable, beamforming, and more- Detailed illustrations and design files
MIMO Antenna Systems for 5G and Beyond is ideal for practicing engineers, as well as researchers in wireless and radio engineering sectors.
